[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1-4 The steel strand bender of this embodiment includes a fixed sleeve 1, one end of which is rotatably connected to a movable frame 2, a side wall of the movable frame 2 is threadedly connected to a first bolt 3, one end of the first bolt 3 is rotatably connected to an extrusion block 4, the fixed sleeve 1 is a hook-shaped structure, the movable frame 2 is an L-shaped structure, and the extrusion block 4 cooperates with the inner wall of one end of the fixed sleeve 1 to clamp and bend the steel strand.

[0026] like Figure 1 As shown, the structure of the steel strand bender in the utility model is similar to the existing steel strand bender structure, such as the prior art CN204947463U. The main improvement of the utility model is to facilitate the bending and installation of the steel strand; when the steel strand needs to be connected to the ground anchor stone and bent and locked by the locking sleeve, the end of the steel strand is first passed through the hanging ring on the ground anchor stone (the ground anchor stone is the prior art, see the specific Figure 1) Since the steel strand itself has a certain degree of bendability, the fixing sleeve 1 is sleeved outside the main line of the steel strand, and the steel strand is passed through one end of the hanging ring, bent to a certain extent and then placed into the fixing sleeve 1. At this time, the movable frame 2 is rotated so that the movable frame 2 is parallel to the fixing sleeve 1. The movable frame 2 and the fixing sleeve 1 restrict the bent steel strand. Then, the first bolt 3 is rotated. The first bolt 3 drives the extrusion block 4 to move. The extrusion block 4 pushes the bent end of the steel strand to make it close to the main line of the steel strand. The inner wall at one end of the fixing sleeve 1 blocks the main line of the steel strand until the bent end of the steel strand abuts against the main line of the steel strand, enabling the steel strand to achieve a 180° bend. At this time, a locking sleeve can be used to lock the bent end of the steel strand and the main line of the steel strand (the locking sleeve is a common hardware part used to fix the steel strand after bending and is not shown in the figure), which facilitates the bending and fixing of the steel strand.

[0027] As Figure 3 shown, relief openings 8 are provided on the upper surfaces of both the fixing sleeve 1 and the movable frame 2. The relief openings 8 are used to make way for the fixation of the bent steel strand. The locking sleeve can lock the bent end of the steel strand and the main line of the steel strand through the relief of the relief openings 8, making the locking part of the steel strand close to the ground anchor stone, enabling the bent end of the steel strand to be left shorter, facilitating the fixation of the steel strand to the ground anchor stone, and reducing the waste of the steel strand.

[0028] As Figures 2-4 shown, the number of the first bolts 3 is two, and the two first bolts 3 are respectively located on both sides of the relief opening 8. Through the two first bolts 3, with the extrusion of the extrusion blocks 4 at their ends on the bent end of the steel strand and the main line of the steel strand, the part of the bent end of the steel strand and the main line of the steel strand located at the relief opening 8 is completely fitted, thus facilitating the locking of the steel strand by the locking sleeve.

[0029] As Figures 1-4 shown, the end parts of the movable frame 2 on both sides of the relief opening 8 are respectively rotatably connected to the end parts of the fixing sleeve 1 on both sides of the relief opening 8. Due to the relief of the relief opening 8, the movable frame 2 is provided with two rotations with the fixing sleeve 1, improving the connectivity between the movable frame 2 and the fixing sleeve 1.

[0030] As Figure 3 shown, two limiting grooves 7 are provided on the inner wall of the movable frame 2. One ends of the two extrusion blocks 4 located at the ends of the two first bolts 3 are respectively slidably connected to the inner walls of the two limiting grooves 7. The limiting grooves 7 restrict the extrusion blocks 4. When the extrusion blocks 4 move, one end of them slides in the limiting grooves 7, and the limiting grooves 7 restrict the extrusion blocks 4, improving the stability of the extrusion blocks 4.

[0031] As Figures 1-4As shown, an arc groove 9 is provided on one side of the extrusion block 4, and the inner wall of one end of the fixing sleeve 1 is an arc-shaped structure; because the outer wall of the steel strand is circular, the arc groove 9 and the arc-shaped structure of the inner wall of the fixing sleeve 1 can stably clamp the bent end of the steel strand and the main line of the steel strand, and the clamping is strengthened and high, which is convenient for the locking sleeve to lock the steel strand.

[0032] like Figure 1 and Figure 4 As shown, one side of the fixed sleeve 1 and one side of the movable frame 2 are fixedly connected with a hook 10; the hook 10 is hung outside the hanging ring on the anchor stone, and then when the steel strand is bent, the fixed sleeve 1 and the movable frame 2 will not be far away from the anchor stone, so that the locking part of the steel strand is close to the anchor stone.

[0033] like Figure 2 and Figure 3 As shown, a socket 5 is provided at one end of the fixed sleeve 1, and a second bolt 6 is threadedly connected to one side of the movable frame 2, and the second bolt 6 is movably plugged into the socket 5; when the movable frame 2 is rotated to be parallel to the fixed sleeve 1, the second bolt 6 is rotated to be inserted into the socket 5 on the end face of the fixed sleeve 1, so that the movable frame 2 cannot rotate, thereby improving the stability of bending the steel strand.

[0034] The implementation steps in this embodiment are as follows: when it is necessary to connect the steel strand to the anchor stone and bend it and lock it with the locking sleeve, first pass the end of the steel strand through the hanging ring on the anchor stone. The steel strand itself has a certain degree of flexibility. The fixing sleeve 1 is set outside the main line of the steel strand, and one end of the steel strand passing through the hanging ring is bent to a certain extent and then placed in the fixing sleeve 1. At this time, the movable frame 2 is rotated to make the movable frame 2 parallel to the fixing sleeve 1, and the second bolt 6 is rotated to make the second bolt 6 inserted into the insertion hole 5 on the end face of the fixing sleeve 1, so that the movable frame 2 cannot rotate, and then one side of the fixing sleeve 1 and the hook 10 on one side of the movable frame 2 are hung outside the hanging ring on the anchor stone. The movable frame 2 and the fixing sleeve 1 restrict the bent steel strand, and the hook 10 makes The fixed sleeve 1 and the movable frame 2 will not move away from the anchor stone. At this time, the two first bolts 3 are rotated again, and the first bolts 3 drive the extrusion block 4 to move. One end of the extrusion block 4 slides in the limiting groove 7. The limiting groove 7 restricts the extrusion block 4. The extrusion block 4 pushes the bent end of the steel strand to make it close to the main line of the steel strand. The inner wall of one end of the fixed sleeve 1 blocks the main line of the steel strand until the bent end of the steel strand located in the yielding opening 8 and the main line of the steel strand are offset, so that the steel strand is bent 180°. At this time, the locking sleeve can be used to lock the bent end of the steel strand and the main line of the steel strand at the yielding opening 8. After locking, the second bolt 6 is separated from the socket 5, the movable frame 2 is turned up, and the fixed sleeve 1 is taken out from the steel strand.

[0035] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
